MACHINE FOR SLOTTING METALLIC GAS-TIPS.

SPECIFICATION forming part of Letters Patent No. 391.35 1, dated October 16, 1888.

Application filed March 12, 1888.

To all whom, it may concern:

Be it known that 1, WILLIAM CAREY, a citi-' zen of the Dominion of Canada, residing in the city and district of Montreal, and Province of 5 Quebec,Canada,have invented certain new and useful Improvements in Punching-Machines for Making Slots in Metallic Gas-Tips; and I do hereby declare that the following is a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a punching-machine for making slots in metallic gas-t ips, which can cut them out of any required width-a thing which is impossible to do with a saw, for when the latter comes into contact with the rounded metallic surface of the gas-tip it vibrates, and thus cuts the slot wider than the thickness of the saw.

My invention has reference to a punchingmachine for making slots in gas-tips, in which there are two punches made to come down on the metallic gas tip, which is placed over a suitable die, the punches making acertain angle with the vertical and acting one after the other in such a way that each punch cuts out half of the slot, as explained hereinafter.

eferring to the drawings, similar letters refer to similar parts throughoutthe several 0 views.

Figure l is a front elevation; Fig. 2, a side view; Fig. 3, a plan view of apart of the main shaft; Fig. 4, a section of the die; Fig. 5, an elevation of the gastip, and Fig. 6 a section 55 of same, showing the slot.

My punching-machine consists of the loose pulley A, mounted on the shaft 13, which is held in position by the standards C, which can be cast with the frame L or not, as found suit- 0 able, the former being provided with the two crank-pins D D, placed as shown in Fig. 8. To these are joined the two connecting-rods E F, through their boxes G H. The connecting-rods E F are made as shown in Figs. 1

and 2, and are joined to the punches I J by means of the ball-bearings K. These punches l J arekept in position by means of the guides M,fixed to the frame L by means of the screws N. These punches I J are provided at their lower extremities, T, with the cutters Q R,

which are made of the same. thickness as the Serial No. 266,975. (No model.)

width of the slot they have to out out. These cutters Q R are firmly secured in the bases 1 r by means of the screws 8, the bases r in turn being inserted into the ends T of the punches I J and firmly held there by means of the screws V.

The metallicgas-tip \V to be slotted is placed on the die 0, as shown in Fig. 4 in dotted lines, and which is provided with a suitable base, Y, the whole firmly secured to the base X of my machine by means of the clamps P P, provided with the screws 1) p. The pulley A is made loose, so that the punches can be made to act only when required by means of the clutch Z, which is operated by the lever to. This clutch Z may be made in any suitable style, its object being merely to couple and uncouple the loose pulley A to the shaft 13. Now, as it would be next to impossible to'cut the 0 slot h in the die 0, Fig. 4, of the exact width were it to be in one piece, I make my die 0 in two equal halves, b d, the sloth being filed out to the right width. The two equal halves b and d are secured together by inserting them 5 into the base Y, which extends to 3 to afford a firm hold. The lower extremity, t, of the die 0 is threaded, so that it is held firmly down by means of the nut l.

The action of my punching-machine is very simple. The gas-tip to be slotted is put on the die 0, as shown in dotted lines in Fig. 4, and the loose pulley A is coupled onto the shaft B by means of the clutch Z, thus starting the punches I and J, which, on account of the cranlcpins D being placed as shown in Fig. 3, come down one after the other, each punching out one-half of the slot in the gastip.

Instead of having two punches inclined, I 0 could employ only one punch placed vertically, only in this case I would be obliged to incline the die, for the simple reason that a vertical punch coming down on a vertical die does not make agoodslot. Ofcourse inthis easel would 5 have to make some provision for the reversing of the die, so that in each descent of the punch one-half of the slot would be punched out.

Having described myinventiomwhatl claim, and desire to secure by Letters Patent, is-
